Quiz (Sections 3.1-3.3)

Unit 3 - Day 4

Writing a Precalculus Assessment
  • Include questions in multiple representations (graphical, analytical, tabular, verbal)

  • Write questions that reflect learning targets and require conceptual understanding

  • Include multiple choice and short answer or free response questions

  • Determine scoring rubric before administering the assessment (see below)

  • Offer opportunities to practice with and without calculators throughout the year

Questions to Include
  • Determine if a relation models exponential growth or decay by analyzing a scenario, an equation, a table, or a graph

  • Write an exponential function from a scenario

  • Graph exponential functions and identify horizontal asymptotes and key points

  • Find the amount in an account at the end of a specified term with compound interest formulas

  • Use “e” to model continuous exponential growth (interest compounded continuously)

Grading Tips

Look for more than just correct answers. Give students feedback on their justifications, communication, and mathematical thinking. We recommend that you prepare a rubric for the free response and short answer items before you begin grading your quizzes or tests. Know what information is necessary for a complete and correct response and award points when a student presents that information. Many of the “Why did I get marked down?” questions are eliminated when you share the components that earn  points.

Reflections

Have students explain how they know something is exponential to assess them on the use of precise language. Give them the horizontal asymptote and y-intercept and have them write an equation.  Make sure the quiz assesses a mix of skills the students can do with a calculator/Desmos and their knowledge of the concepts.  They often see a percent and automatically think it’s exponential, so challenge them with different scenarios like the questions from the Check Your Understandings that require extra thought.
